On our web site we have a page that includes mp3 files, which play okay on Firefox; but on another page on the site with mp3 files, Firefox (including different versions on different computers) produces the error message, No video with supported format and MIME type found." FWIW, other browsers like Safari (Mac), Chrome (Mac and Win), and Edge (Win) all play the problematic files without a hitch.

Is there a fix for this problem that can be attempted by the non-tech types?

I get a weird green mark on the top left, which looks like some type of greenscreen cursor input thing. I have seen it on Gmail. Not sure where else. Last time was a while ago.

This is on Windows 11. Just worried if this is some type of backdoor thing.

I cannot figure out why this important site which I have used for years is suddenly being blocked. the message I'm getting says-"Firefox has detect that the server is redirection the requested address in a way that will never complete. This problem can sometimes be caused by disabling or refusing cookies." I don't believe I have made any changes to cookies or anything else in the past few days so I don't know what to fix.

Please help

Hello, I encountered an error when trying to install the extension. I've never encountered anything like this before

Some sites stopped opening, although in other browsers, and through the phone everything opens up. I've tried reinstalling the browser, disabling extensions, resetting DNS. It didn't help. A list of sites I'm having trouble with: https://www.deepl.com/ https://enka.network/ https://7tv.app/ https://hsr.hakush.in/ and some other sites that I can't remember right now. In Chrome he working. Sites like youtube twitch and other poplar working too, idk why firefox have problem, maybe its new update?

I have been a devoted Firefox users for many years. Just in the past week or so I have started having multiple tabs crash daily and now am getting 1 or 2 blue screens a day. I run on Windows 11 Pro. What can I do to help this issue?

Since the auto-update to version 128.0.3 (64-bit) two weeks ago, my Firefox crashes as soon as I switch over to a different programme. I am on Windows 10. Whenever I try to re-open the programme, I get the error message that Firefox is already running and if I want to restart or quit. Can you please deploy a fix for this? Thank you.

After your an update some weeks ago, I have not been able to access my bank account using Firefox. Got some advice from support from the bank, but since I have an US version, the labels to be accessed differed, and were not compatible with the advice. Presently using M Edge, which I of several reasons don`t want to. Any suggestions?

The fucking forced dark mode has return despite the previous fix layout.css.prefers-color-scheme.content-override = 1 in about:config fixing it for years. This and the current replacement fixes don't save. I want a solution for PERMANENT light mode (black text on white background) for ALL menus, pop-ups, dropdown menus and hover over tab info.

And don't tell me to go search for a different theme I've already spent hours doing that and firefox has broken them only making some menus use the appropriate mode. On top of that I can't even pick an option to search for one that uses light mode I just have to go through each one and try it if I want to know which mode it uses that is NOT a solution to anything.

Replacement "fixes" for reference: ui.systemUsesDarkTheme won't even let me set to 0 only has true/false browser.theme.content-theme set to 1 browser.theme.toolbar-theme set to 1 (Why in the absolute hell these were added when a simple addition to preference setting wasn't is beyond me)

Very sorry for the aggressiveness but I am so very VERY tired of having to fight firefox on this preferance for years when their dark mode hurts my eyes.

It seems more and more websites refuse or deny FF as an acceptable browser. My bank, my electricity provider are just two examples.

Is this being addressed?

Is there a feature or add-on that will allow me to see all of my tabs, about 60, in a double menu instead of crammed, forcing me to use the horizontal arrows to scroll? I'd prefer to see them all at once and have them accessed immediately.

What is this tab, and why is it hidden? My usually good Google-fu didn't turn up much other than TrustArc is a cookie consent component with a terrible reputation for slowing down some sites that use it.

Can someone offer more information? Thanks.
